WILHELM HERBST, 0F BERLIN-$TEGLITZAND EMIL DIECKMANN, OF BARMEN- UNTERBARMEN, GERMANY.

FIREPROOF FLOOR CONSTRUCTION.

Specification of Letters Patent.

, Patented Dem-29, 190s.

To all whom it may concern:

Be it known that we, WILHELM HERBST and EMIL DIECKMANN, both citizens of Germany, and residents, res ectively, of 'erlin- Steglitz and Barmen- Jnterbarmen, Germany, have invented new and useful Improvements in Fireproof Floor Construction, of which the following is a specification.

This invention relates to a fireproof 1100: construction which is strong, light, simple, and permits the parts to be readily assembled and fitted. r

In the accompanying drawings: Figure 1 is a longitudinal section of a floor construction embodying my invention; Fig. 2 a cross section on line A-B, Fig. 1; Fig. 3 a

longitudinal section of a modification; Fig. 4

a cross section on line CD, Fig. 3; Fig. 5 a longitudinal section of. a further modification; Fig. 6 a cross section on line EF, Fig. 5; Fig. 7 a detail of one form of floor beam; Fig. 8 a detail of one form of transverse hollow block; Fig. 9 a detail of one form of top plate; Fig. 10 a detail of one form of bottom plate; Fig. 11 a cross section of a further modificatlon of the floor construction; Fig. 12 a section on line JH, Fig. 11, and Fig. 13 a section on line K-L, Fig. 11.

A series of parallel longitudinal beams or ribs 7, made preferably of cement or iron, beton, are provided at each side with a lower ledge 8. These ledges may extend either over the entire width of beams 1', or over but part of the same, the latter construction being shown in Fig. 7. Upon the opposed ledges of adjoining beams are sup orted a number of spaced transverse hollow locks a, made of cement or other suitable material. These blocks are provided with an integral base a, and laterally extending projections 0 adapted to rest upon ledges s, 'so' that i in this Way the blocks are. securely seated upon the beams. are supported top bases a, of such b cks are supported base plates 1;, havin flanges c, that overliesuch ases. Plates 0, may be composed of suitable material, such as ash beton, burnt or U on adjoining blocks a,

bakedclay, and also of elastic metal, wire netting, etc.

Beams 1', roject with-their upper ends into a beton ayer i, which unites with the beams to form an integral structure adapted to sustain the floor weight. The bottom plates a, carry a layer of ceiling plaster g.

1pates 6, while upon the what longer than those shown in Figs. 1 and 2, so that the construction is ada ted more particularly forroofs or floors ma e to bear 'ght weight. w

In Figs. 5 and 6, beams r, are arranged in close proximity to each other, and blocks a, are correspondingly shortened.

In Figs. 3 and 4, the blocks a, are some- In Fig. 11 the beams 1', extend beyond the front wall m, of the building, while the beton layers '5, 'i, are carried by plates 1), 0, respectively, according to static conditions.

In Fig. 13, there is carried by lates b, a fillingf, of sand or ashes, u onw 'ch the floor layer e, is supported, Whl e beton layer '11, IS

the ower ends of beams a.

We claim:

supported on bottom plates 0, and embeds 1. A fire proof floor construction, comprising a series of longitudinal iron beton beams, spaced transverse blocks supported thereon, top Iplates and bottom plates supported by the locks, and a beton layer embedding the upper ends of the specified;

2. A fire proof floor construction, comprising a series of longitudinaliron beton beams, spaced transverse blocks supported thereon,

beams, substantially as top plates and bottom lates supported by the blocks, a first beton ayer embedding the upper ends of the beams,'and a second beton layer embedding the lower ends of the beams,

substantially as specified.

3. A fire proof floor construction, comprising a series of longitudinal beams having ledges, spaced hollow blocks having integral bases-and projections engaging the ledges, top plates supported upon the blocks, a beton layer supported on the top plates and bottom plates supported upon the integral bases, substantially as specified.

Signed by us at Barmen, Germany, this 27th day of April 1908.
